Renal glycosuria

This code represents a condition characterized by the excretion of glucose in the urine despite normal blood glucose levels. It results from a defect in the renal tubules' ability to reabsorb glucose, leading to glucosuria without hyperglycemia.

Use this code when documentation indicates the presence of glucose in the urine with a normal or low blood glucose concentration, confirming a primary renal tubular defect. This diagnosis is typically made after ruling out diabetes mellitus and other causes of hyperglycemia.

• Differentiate from diabetes mellitus (250.xx) where hyperglycemia is present.
• Ensure documentation explicitly states "renal glycosuria" or describes the presence of glucosuria with euglycemia.
• Do not use for transient glucosuria due to high carbohydrate intake or medications unless a renal tubular defect is confirmed.
